A lying, unprincipled, selfless person whose dirth of self-respect compels him to desperately sell himself to any buyer. He derives all his self-respect second-hand from others, but he can never fill the bottomless pit where his ego belongs. He lacks serious convictions and has no heroes; he lacks the confidence and courage to hold and form his own opinions. He is not a man, but a mouthpiece of the fools whose approval he cherishes.

After mid terms, in State of the Union address-
Bill Clinton: "The era of big government is over!"

Observer: "Damn, that Clinton fool is such a politician. Does he believe in anything, or does he just say what people want to hear?"

Example 2:
George Bush: "I will never support anything resembling a national healthcare system."

Two years later, signing Prescription Drug Act
George Bush: "Now, a single payer, the government, will buy your medications!"

Observer: "Damn, just two years ago he said he didn't want government involved in healthcare. Did he really believe that, or was he just being a politician and saying that because that's what people wanted to hear at the time?"
